ETHERNET
CONNECTION
When connecting to MELSEC-FX
*1 The destination connected with the twisted pair cable varies with the configuration of the applicable Ethernet network system.
Connect to the Ethernet module, hub, transceiver or other system equipment corresponding to the applicable Ethernet network
system.
Use cables, connectors, and hubs that meet the IEEE802.3 10BASE-T/100BASE-TX standard.
A cross cable is available for connecting the GOT to the Ethernet module.
*2 When connecting GT16 of the function version A to an equipment that meets the 10BASE (-T/2/5) standard, use the switching
hub and operate in a 10Mbps/100Mbps mixed environment.
For how to check the function version, refer to the following.
GT16 User's Manual (Hardware)
*3 A length between a hub and a node.
The maximum distance differs depending on the Ethernet device to be used.
The following shows the number of the connectable nodes when a repeater hub is used.
• 10BASE-T: Max. 4 nodes for a cascade connection (500m)
• 100BASE-TX: Max. 2 nodes for a cascade connection (205m)
When switching hubs are used, the cascade connection between the switching hubs has no logical limit for the number of
cascades.
For the limit, contact the switching hub manufacturer.
*4 For the system configuration of the Ethernet module, refer to the following manuals.
For FX Ethernet Interface Module User’s Manual
*5 Select one of the following [Controller Type] in [Ethernet] of GT Designer3.
• Ethernet module (FX Series): FX
For [Ethernet] of GT Designer3, refer to the following.
